Mistress Sabrina, clad in delicate yet imposing black lingerie, stood towering over her unsuspecting victim. Her legs were long and toned, accentuating the perfect roundness of her ass, which she leaned towards him ever so slightly, inviting him to take a whiff of the sweet scent of her freshly wiped behind. The loser lay on the ground, his hands tied behind his back and his head bowed low in submission. He could feel the softness of the plush carpet against his skin and the slight coolness of the air conditioning on his bare chest. Still, he knew that this pleasure would be short-lived as he awaited the punishment that Mistress Sabrina had in store for him. Without further ado, Mistress Sabrina slowly lowered herself down onto his face, trapping him beneath her massive ass. She took her time, savoring the power she had over him as she leaned over him, her breasts almost touching his chin. The warmth of her body radiated against his face, causing him to slip further into subspace. As soon as she felt him sink under her control, Mistress Sabrina pressed her perfect round ass down onto his face, ensuring that she wedged his nose deep between her cheeks. She grinned wickedly as he began to struggle for air, his face turning an alarming shade of red. She knew that he couldn't breathe properly with her sitting on him like this, and she loved it. Mistress Sabrina continued to sit on his face, mercilessly crushing him beneath her massive weight. She reached down and began to massage his cock through his pants, alternating between gentle strokes andrough, jabbing motions that sent waves of pleasure and pain coursing through his body. As she felt his orgasm building up inside him, Mistress Sabrina began to rock back and forth, grinding her ass against his face in perfect rhythm with the growing intensity of his climax. She was in control, and she intended to keep it that way. Finally, after what felt like an eternity, Mistress Sabrina removed herself from his face, leaving him gasping for air. She stood up and admired herself in the mirror, making sure that her makeup was perfect and her lingerie was still in place. She turned back to him, smirking. "Do you want more, slave?" she purred, her voice dripping with menace. The loser nodded frantically, unable to speak past his immediate need for another taste of her perfect ass. "Very well," she said, her voice steeped in anticipation. "Get ready for round two." With that, Mistress Sabrina lowered herself back down onto his face, ready to continue their heated facesitting session. The loser could do nothing but submit as she sat upon him once more, his face pressed firmly against her ass cheeks, helpless in the grip of his own desire.
